Abstract
A screen for separating solids and liquids is formed from parallel strips of wedge wire or similar material into a two-sided enclosure having the flat bases of the wedge wires oriented to contact dirty liquid. Unfiltered liquid containing solids contacts the screen surface on both sides of the enclosure, forming a passage for filtrate. A wedge wire screen may be bent back on itself to form a C-shape or may be a closed curve, still exposing only the flat sides of the wedge wires to the dirty liquid, and collection filtrate within the enclosure so formed. Filter units may be placed in a housing adapted to accommodate two or more in a substantially concentric relationship.
